HARNESS STAND AND STOP MOTION FOR LOOlVIS.

Application filed July 11, 1921. Serial No. 483,800.

To all whom it may concern Be it known that we, EDWARD M. lVHAR- TON and JOHN W. Jones, citizens of the United States, residing at Greenville, in the county of Greenville and State of South Carolina, have invented new and useful Improvements in Harness Stands and Stop Motions for Looms, of which the following is a specification.

This invention relates to a harness stand and stop motion for looms, the principal object of the invention being to provide means for automatically stopping the loom if the harness should break or stretch. or any part of its assembly give way so as to interfere with the movement of the shuttle.

Another object of the invention is to provide means whereby the attachment can be made adjustable to conform to the loom upon which it is used.

Another object of the invention is to provide means whereby the device will. operate. with the ordinary stop motion of the loom.

Another object is to provide a stand upon which the harness will rest when any portion of the harness (its straps, hooks or equipment) breaks or stretches, thus causingthe harness hame to drop from its usual position onto said stand so that said stand will prevent the harness from dropping onto the floor.

This invention also consists in certain other features of construct-ion and in the combination and arrangement of the several fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or correspondingparts throughout the several views. and in whic i l ipgure II, is an end view. larnel y diagramn'iatie, slmwing our invention in use with a loom.

Figure 2 showing the invention in Figure 3 is a view itself.

Figures 4. and 5 are fragmentary views showing a modification.

As shown in these views the attachment comprises the base 1 which is adapted to be secured fast to the floor. An upright 2 is connected with said base and an upright 3 is an enlarged sectional. view use. of the attachment .it will fall on the is adjustably secured to the upright 2 by the bolts and slots 4. The upper end. of upright 3 is of fork shape with the extremities of the arms of the fork bent upwardly to form the vertical parts 5. One of these vertical parts is provided with a hole 6 and the other with a slot 7 for forming bearings for the crank rod 8, this rod being suitably secured in position. One end of the rod is extended, as at 9, and this extension is provided with a bent part 10 which passes through a block 11 and is adjustably secured thereto by the bolt 12. An arm 13 is adjustably secured to the block by the bolt 14. A stud 15 projects from one of the vertical parts 5 and engages the crank part of the rod 8 to hold the same in position. We prefer to make one of the end pieces of the crank of rod 8 longer than the other, as shown in Figure 3, so as to place the bight of the crank substantially parallel with the lower edges of the harness, it being understood that said lower edges of the harness are not in a horizontal plane but are arranged in an inclined plane.

As shown. in Figures 1 and 2, one of these devices is placed beneath the loom directly under the harness and one at each end of the harness. The devices are adjusted in height to suit the loom, by means of the bolts and slots 4 and the crank of rod 8 rests at an angle of about 15, this rod being held in this position by the stud 15. Arm 13 extends at an angle of about 15 in an opposite direction from the crank of rod 8 so that it will not interfere with the normal operation of the loom. However, if any portion of the harness should break or if it should stretch beyond its natural position rod 8, thus causing the rod to tilt and move arm 13 upwardly into the stop motion comb and thus automatically stop the loom.

Our invention. will prevent damaging of the cloth in process of manufacture and thus eliminate seconds. The device will not interfere with the proper running of the loom nor will it conflict with any stop motion now in use as it will only come into operation when any part of the harness breaks or stretches and thus interfere with the movement of the shuttle.

Figures 4 and 5 show a modification in which the arm 13 is provided with a hook at its upper end for engaging an arm 13 which is bolted to the stop motion comb.

In other respects this form of the device is similar to that first described.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

We desire it to be understood that we may make changes in the construction and in the combination and arrangement of the sevoral parts, provided that such changes fall within the scope of the appended claims.

W hat we claim is 1. A heddle stop motion device comprising a stand, a rod rotatably mounted therein and provided with a crank part, the bight of which is of considerable length and is adapted to be placed under the harness and an arm connected with one end of the rod for engaging the stop motion when the crank is engaged by the harness.

2. Aheddle stop motion device comprising a stand, a rod rotatably mounted therein 1 ,aeanm and. provided with a crank part, the bight of: which is of considerable length and is adapted to be placed under the harness and an arm adjnstably connected with one end of the rod for engaging the stop motion when the crank is engaged by the harness.

A heddle stop motion device comprising a stand l'iaving a forked upper end, a rod having parts rotatably mounted in the prongs of the tork, said rod having a (rank part located between the prongs, the bight of which is adapted to be placed under the harness and an arm connected With one end of the rod for engz'tging the stop motion of the loom when the rod is moved by the harness engaging the crank part.

In. testimony whereof we alhX our signatures.
